Abstract

An RC type oscillator (10) is integrated into a processor circuit (2) of a mobile device (1). This oscillator is used to set the pace of the activity of the processor circuit during periods when the mobile device is on standby. The frequency drift due to the temperature variations of the oscillator is concerted by a regular calibration of the oscillator by a faster oscillator recognized to be stable. This embodiment gives gain in space and a reduction in cost.
